INSTALLATION OF RADIO TRANSMITTING

EQUIPMENT

Special design considerations are incorporated into this

vehicle’s electronic system to provide immunity to radio

frequency signals. Mobile two-way radios and telephone

equipment must be installed properly by trained person-

nel. The following must be observed during installation.

The positive power connection should be made directly

to the battery and fused as close to the battery as possible.

The negative power connection should be made to body

sheet metal adjacent to the negative battery connection.

This connection should not be fused.

Antennas for two-way radios should be mounted on the

roof or the rear area of the vehicle. Care should be used

in mounting antennas with magnet bases. Magnets may

affect the accuracy or operation of the compass on

vehicles so equipped.

The antenna cable should be as short as practical and

routed away from the vehicle wiring when possible. Use

only fully shielded coaxial cable.

Carefully match the antenna and cable to the radio to

ensure a low Standing Wave Ratio (SWR).

Mobile radio equipment with output power greater than

normal may require special precautions.

All installations should be checked for possible interfer-

ence between the communications equipment and the

vehicle’s electronic systems.

WARNING:

Operating, servicing and maintaining a

passenger vehicle or off-road highway

motor vehicle can expose you to chemicals

including engine exhaust, carbon monoxide,

phthalates, and lead, which are known to

the State of California to cause cancer and

birth defects or other reproductive harm.

To minimize exposure, avoid breathing

exhaust, do not idle the engine except as

necessary, service your vehicle in a

well-ventilated area and wear gloves or

wash your hands frequently when servicing

your vehicle. For more information go to

www.P65Warnings.ca.gov/passenger-vehicle.

VEHICLES SOLD IN CANADA

With respect to any Vehicles Sold in Canada, the name

FCA US LLC shall be deemed to be deleted and the name

FCA Canada Inc. used in substitution therefore.

DRIVING AND ALCOHOL

Drunken driving is one of the most frequent causes of

accidents.

Your driving ability can be seriously impaired with blood

alcohol levels far below the legal minimum. If you are

drinking, don’t drive. Ride with a designated non-

drinking driver, call a cab, a friend, or use public trans-

portation.

WARNING!

Driving after drinking can lead to an accident.

Your perceptions are less sharp, your reflexes are

slower, and your judgment is impaired when you

have been drinking. Never drink and then drive.

This manual illustrates and describes the operation of

features and equipment that are either standard or op-

tional on this vehicle. This manual may also include a

description of features and equipment that are no longer

available or were not ordered on this vehicle. Please

disregard any features and equipment described in this

manual that are not on this vehicle.

FCA US LLC reserves the right to make changes in design

and specifications, and/or make additions to or improve-

ments to its products without imposing any obligation

upon itself to install them on products previously manu-

factured.

INTRODUCTION

Dear Customer, congratulations on selecting your new

vehicle. Be assured that it represents precision workman-

ship, distinctive styling, and high quality.

This is a specialized utility vehicle. It can go places and

perform tasks that are not intended for conventional pas-

senger vehicles. It handles and maneuvers differently from

many passenger vehicles both on-road and off-road, so

take time to become familiar with your vehicle. If

equipped, the two-wheel drive version of this vehicle was

designed for on-road use only. It is not intended for

off-road driving or use in other severe conditions suited for

a four-wheel drive vehicle. Before you start to drive this

vehicle, read the Owner’s Manual. Be sure you are familiar

with all vehicle controls, particularly those used for brak-

ing, steering, transmission, and transfer case shifting.

Learn how your vehicle handles on different road surfaces.

Your driving skills will improve with experience. When

driving off-road, or working the vehicle, don’t overload the

vehicle or expect the vehicle to overcome the natural laws

of physics. Always observe federal, state, provincial and

local laws wherever you drive. As with other vehicles of

this type, failure to operate this vehicle correctly may result

in loss of control or a collision. Refer to the “Driving Tips”

in “Starting and Operating” for further information.

This Owner’s Manual has been prepared with the assis-

tance of service and engineering specialists to acquaint you

with the operation and maintenance of your vehicle. It is

supplemented by Warranty Information, and customer

oriented documents. In the attached Warranty Booklet you

will find a description of the services that FCA offers to its

customers, the Warranty Certificate and the details of the

terms and conditions for maintaining its validity. Please

take the time to read all of these publications carefully

before driving your vehicle for the first time. Following the

instructions, recommendations, tips, and important warn-

ings in this manual will help assure safe and enjoyable

operation of your vehicle.

This Owner’s Manual describes all versions of this vehicle.

Options and equipment dedicated to specific markets or

versions are not expressly indicated in the text. Therefore,

you should only consider the information which is related

to the trim level, engine, and version that you have

purchased. Any content introduced throughout the Own-

er’s Information, that may or may not be applicable to your

vehicle, will be identified with the wording “If Equipped”.

All data contained in this publication are intended to help

you use your vehicle in the best possible way. FCA aims at

a constant improvement of the vehicles produced. For this

reason, it reserves the right to make changes to the model

4 INTRODUCTION

described for technical and/or commercial reasons. For

further information, contact an authorized dealer.

If applicable, refer to the Owner’s Manual Supplement for

related information.

NOTE: After reviewing the Owner’s Information, it should

be stored in the vehicle for convenient referencing, and

remain with the vehicle when sold.

When it comes to service, remember that your authorized

dealer knows your vehicle best, has factory-trained techni-

cians and genuine MOPAR® parts, and cares about your

satisfaction.

ROLLOVER WARNING

Utility vehicles have a significantly higher rollover rate

than other types of vehicles. This vehicle has a higher

ground clearance and a higher center of gravity than many

passenger vehicles. It is capable of performing better in a

wide variety of off-road applications. Driven in an unsafe

manner, all vehicles can go out of control. Because of the

higher center of gravity, if this vehicle is out of control it

may roll over while some other vehicles may not.

Do not attempt sharp turns, abrupt maneuvers, or other

unsafe driving actions that can cause loss of vehicle con-

trol. Failure to operate this vehicle safely may result in a

collision, rollover of the vehicle, and severe or fatal injury.

Drive carefully.

Rollover Warning Label

1

INTRODUCTION 5

Failure to use the driver and passenger seat belts provided

is a major cause of severe or fatal injury. In fact, the U.S.

government notes that the universal use of existing seat

belts could cut the highway death toll by 10,000 or more

each year and could reduce disabling injuries by two

million annually. In a rollover crash, an unbelted person is

significantly more likely to die than a person wearing a seat

belt. Always buckle up.
